Question

In the below html tags, I want to use c# programs to remove the whole tags which has the attribute values "display:none" in style:

<td>
    <span style="display:none">
        <font color="#ffffff">OK</font>
    </span>
    <span>
    <font color="#ffffff">OK</font>
    </span>
</td>

and the html will become:

<td>
    <span>
        <font color="#ffffff">OK</font>
    </span>
</td>

Besides using Replace() function, Can anyone suggest me some ways to solve this problem?

Fortunately you can use jQuery like sintaxys in C# using CsQuery

string htmlString = @"<td>
<span style=\"display:none\">
<font color=\"#ffffff\">OK</font>
</span>
<span>
<font color=\"#ffffff\">OK</font>
</span>
</td>";
var dom = CQ.Create(htmlString);
dom.Select("[style=display:none]").Remove();

I don’t test it but is a good starting point

In a DOM with more than one display:none, as metioned @jamietre in comments

var dom = CQ.Create(htmlString);
dom.Select("[style]").Where(item=>item.Style["display"]=="none")).Rem‌​ove();
